Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64544, here are decompositions:

  • 31 + 64513 = 64544
  • 61 + 64483 = 64544
  • 163 + 64381 = 64544
  • 211 + 64333 = 64544
  • 241 + 64303 = 64544
  • 307 + 64237 = 64544
  • 313 + 64231 = 64544
  • 373 + 64171 = 64544

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64544 first appears in π at position 159,683 of the decimal expansion (the 159,683ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
